LOCK-HASP.

Specification of Letters Patent No. 14,675, dated April 15, 1856.

To all whom z5 may concern Be it known that I, M. NEWMAN, 2d, of Oak Hill, in the county of Greene and State of New York, have invented certainY new and useful Improvements in Securing-Hasps, called Lock-Hasps; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification.

This improvement is intended to dispense with the unsightly and inconvenient arrangement of a separate lock to secure a latch or hasp over the staple, and the invention consists in attaching the lock immediately to the hasp, said lock so swiveled upon the hasp that a tongue or ear may be introduced and locked into the staple outside of the hasp and prevent its withdrawal from the staple.

To enable others skilled in the art to make and use my improvement I will proceed to describe it as follows. The hasp A and staple B, are of the usual form or construction.

C is a bar pivoted on a projecting pin a, inserted in the hasp; it has projecting ears b, b, so as equally to serve the purpose in applying the latch a right or left hand purpose; the body of the bar C is hollow and forms the casing for the lock d of which e is the bolt, dotted line; on the hasp are projections f, f, f the central one f serving as a rest to the swing bar c, as well as a retainer of the bolt e, when projected from the lock by the turning of the key. The hasp is secured in the usual Inode to the door by a staple upon which it swings.

B is an ordinary staple inserted in the door-jamb with suicient projection t-o allow one of the ears b, of the swing bar C to enter the staple; when the bolt e is projected by turning the key it enters between the projections f f, and thus the ear of the bar C is securely kept in the eye of the staple, and the removal of the hasp can not be effected without the previous removal of the ear, holding it in place. The disadvantage arising from displacement of the lock when separated from the hasp, led to this improvement, which is one eminently useful and simple.

What I claim as my invention and desire to secure by Letters Patent is- The use of the swing bar C, constructed as described in connection with the locking bolt e, and the hasp.A, with projections f f f thereon, for the purpose of retaining the hasp when on the staple, substantially in the manner set forth.

In testimony whereof I have hereunto signed my name before two subscribing witnesses.

M. NEWMAN, 2D.
